JACKSON, MISSISSIPPI.

BOILER-FLU E CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 52 5,699, dated September 11, 1894. Application filed May 31, 1894. Serial No. 513,014. (No model.)

To all whom it may concern:

Be it known that I, PHILLIP HENRY ENOOHS, of Fernwood, Pike county, State of Mississippi, have invented certain new and useful Improvements in Boiler- Flue Cleaners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forminga part hereof.

My invention has relation to improvements in boiler-flue cleaners and consists in the novel arrrangementand combination of parts more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a perspective view of my improved cleaner. Fig. 2 is a middle longitudinal section of the same. Fig. 3 is an end view thereof. Fig. 4 is a section on the line a:w of Fig. 2. Fig. 5 is a side elevation of a modified form. Fig. 6 is an end view of the same. Fig. 7 is an end view of a form having four resilient members or legs each with a scraping plate secured thereto; and Fig. 8 is an end view of a form having three resilient members with scraping plates attached.

The object of my invention is to construct a boiler-flue cleaner which will be simple in construction, adjustable for various sizes or diameters of flues, one which can be varied according to the length of the boiler; one that can be easily inserted into, withdrawn from, and guided withinihe flue. In detail it may be described as follows:

Referring to the drawings, the cleaner portion proper is composed of an iron bar 1 formed by welding at one end the resilient members or legs 2, the free ends of which carry the semi-circular plates 3, constituting the terminal scrapers of the cleaner. The solid portion of the bar 1 carries a sliding or movable washer 4 which is intended to prevent the cleaner from passing through and hanging in the flue. Exterior to the washer is an interiorly screw-threaded nipple 5 into which can be screwed one end of the operating handle 6.

At a suitable point along the length of one of the members 2 is a screw-threaded bolt 7 passing through substantially at right angles to the expanded or flat side or.face of the same, and abutting against the inner face of the opposite member. The bolt carries a head 8 between the opposite faces of the members 2, by turning which the said members can be expanded more or less according to the width or diameter of the flue to be scraped, thus adapting the present device to flues of various diameters.

The semi-circular plates 3 constituting the cleaning flange of the cleaner can be riveted to the expanded ends of the members 2, as shown in Fig. 2, or in practice they may be turned on said members. It is to be'uuderstood of course that I do not limit myself to the precise details of construction. The extreme distance between the washer 4 and the plates 3 should be a fraction of an inch less than the length of the flue to be cleaned so as to prevent the end of the cleaner from dropping and hanging in the flue. For very long flues of course it is obvious that the handle may be extended and the washer 4 shifted so 'as to accord with the increased length of the flue cleaned.

The modified form shown in Figs. 5 and 6 is used in flues which are comparatively of large diameter, say three'inches, the resilient arms or members 9 touching or approaching each other at, or'near their medial portion and then expanding on either side thereof, and having one end secured to a casting 10 which is provided with a screw-threaded socket 11 for the reception of a suitable han- In flues of still larger diameter I may dle. use four or three resilient members in which instance the scraping plates secured to their ends will be either in the form of a quartercircle or one-third of a complete circle as fully indicated in Figs. 7 and 8.

Having described my invention, what I claim is- A boiler-flue cleaner comprising a suitable bar, resilient members secured to or forming a part of said bar, suitable scraping plates at the end of said members, an adjusting bolt having a head carried by one of said members, the head being located between the members, and a suitable operating handle adapted to be secured to said bar, substantially as set forth.

In testimony whereof I affix my signature in the presence of two witnesses. J
